Eternal Isle and Immortal Isle sit off the edge of Aion 2’s two starting continents, walled off from everything else by open ocean. You cannot walk or fly to either one under your own power, and neither has a Kibelisk, so fast travel will never drop you there. The one route in is a Windstream — a glowing blue air current that catches your wings and carries your character across the water automatically.
Eternal Isle belongs to Verteron on the Elyos side. Immortal Isle belongs to Altgard on the Asmodian side. Both are late-region field zones with enemies in the level 49 to 51 band.
Quick answer: Both isles are reachable only by riding a Windstream, and neither has a Kibelisk. Take the Windstream west of Southern Tolbas Forest for Eternal Isle, or the one west of Moslan Forest for Immortal Isle.
Reach Eternal Isle in Verteron (Elyos)
Eternal Isle lies off the southwestern coast of Verteron, the Elyos faction region. Two separate Windstreams lead there, and both drop you at the same point on the island without spending any flight power. Pick whichever launch point is closer to you.
Windstream 1: West of Southern Tolbas Forest
Windstream 2: Aullaeu Village Sky Island
For the second route, start at Aullaeu Village Sky Island, a floating landmass above the continent’s far southwestern edge. Rise from the Forest of Exile fast-travel point, travel south, and land there; then activate the Aullaeu Village Sky Island Kibelisk. The Windstream is on the Kibelisk’s west side. Ride it to reach the same part of Eternal Isle as the first route.
Reach Immortal Isle in Altgard (Asmodian)
Immortal Isle occupies Altgard’s southwestern corner in Asmodian territory. Its sole connection is a Windstream on the cliffs to the west of Moslan Forest, and you must ride it each time you return.
Confirm arrival and plan the return trip
The journey is confirmed when you finish gliding and land on the island’s wooden camp platform. On your first arrival at Eternal Isle, a notification also reports that you have discovered a new region.
Neither isle provides a Kibelisk, so you cannot set up a lasting fast-travel destination or warp between them. To return, you must ride a Windstream again; finish all your activities in one visit instead of departing and coming back.
Keep a teleport scroll on you if you want a quick way off the island once you are done, since the Windstream only carries you one direction.
Level requirement before you ride
Plan to reach level 45 at minimum, since these are upper-tier hunting areas. Enemies span levels 49 through 51; the level 51 elemental spirit guardians are the strongest. Below that level, staying alive—and especially farming—will be difficult.
Drana Mutants are the main regular monster on both islands and the best steady drop source among the normal creatures. They can drop Spiritstone, Refining Stone, and Expert’s Refining Stone.
What to do once you land
Three things are worth your time on either island: the Empyrean Traces scattered across the terrain, the field boss, and the quests set here. Knock them all out in the same visit so you are not riding the Windstream twice.
Collect the Empyrean Traces
Empyrean Traces, or feathers, are densely scattered across both maps and contribute to character progression. Collect as many as possible during your visit; returning to retrieve any overlooked ones takes another trip. Several cubes are also concealed on each island for thorough explorers.
Eternal Gartua and Immortal Gartua
A field boss resides on each island; each is a level 51 Hero-rank enemy found at a single spawn location. They do not attack on sight, yet their damage makes a full party advisable over going solo. Both award an identical gear set: a complete Unique armor set, earrings, a ring, Refining Stones, and boss artwork.
Eternal Gartua spawns in the middle of Eternal Isle, inside an arena ringed by four updrafts. Reach it by riding an updraft from the island path up to the arena. Its map icon hides underneath the Eternal Isle icon, so it is easy to miss. Click the icon to read the respawn timer, or force-select it from Exploration > Field Boss in the map screen.
Immortal Gartua sits in the middle of Immortal Isle as the island’s lone field boss. Same level, same Hero rank, same approach: dodge its line attacks and the two waves of its pulse move, and clear it with a group.
Finish the island quests
Each island offers quests that can only be completed there on the ground. Finish them during your current visit to avoid making an extra Windstream journey.
| Quest | Type | Rec. level | Key reward |
|---|---|---|---|
| Eternal Isle’s Distinct Ecology | Regional | 45 | Title: Transcender of Time |
| Immortal Isle’s Distinct Ecology | Regional | 45 | Title: Going Beyond Time |
| Immortal Isle: Repelling Assault | Duty | 49 | 1,000 Abyss Points |
| Immortal Isle: Protecting the Weak | Duty | 50 | 1,000 Abyss Points |
On the Elyos side, the regional quest Eternal Isle’s Distinct Ecology begins back in Verteron when you talk to Ahtan on a cliff in the southwestern Tolbas Forest. He dreams of studying the island’s mutated Drana but cannot bring himself to ride the Windstream, so he asks you to gather specimens. Ahtan sums up the draw himself: “It’s said to be far from Verteron, with its own unique ecosystem.” Turning it in pays 100,000 Bound Kina, a Wisdom Stone, a Daevanion Crystal, a Soul Codex: Reset, and the Transcender of Time title, on top of a large experience reward.
The Asmodian version, Immortal Isle’s Distinct Ecology, works the same way. It starts in Altgard when you speak to Nivena at the Sanctum Outpost Cliff, who shares Ahtan’s dream but is held back by a fear of heights. She wants Drana Mutant hair and teeth gathered on the island. Finishing it hands over 100,000 Bound Kina, a Wisdom Stone, a Daevanion Crystal, a Soul Codex: Reset, and the Going Beyond Time title.
Immortal Isle also carries two duty quests, Repelling Assault and Protecting the Weak. Both reward 1,000 Abyss Points and repeat infinitely, which makes them a steady point source for anyone farming the island regularly. Repelling Assault tasks you with clearing out Kerubiel, Kerubar, and Kerubian, while Protecting the Weak sends you after Drana Mutants and the Kuru.
Whichever side you play, the loop is the same: ride in with level and gear to spare, collect every feather, clear the quests, and take down Gartua with a party before the Windstream trip is wasted. Since the ride only goes one way and there is no Kibelisk to bring you back, the single most useful habit is treating each visit as a full clear.
